And Ruby Rose was the image of joy when she swung by The Tonight Show Starring Jimmy Fallon for an episode that will air Wednesday evening.

The Melbourne-born 32-year-old showed off her svelte legs in a peekaboo dress that offered up a view of her flat midriff.

Her predominantly black full-sleeved number, which was hemmed at about mid-thigh, featured white polka-dots along the slit that ran down its front.

These same polka dots lined her snappy little collar, and she slid into a see-through pair of lacy black stilettos for her chat-show appearance.

Ruby sat down opposite Jimmy's desk at his Rockefeller Center studio with her face caked in makeup and her cropped hair slicked stylishly back.

As it was announced that she would had been cast as Batwoman for an upcoming series on The CW as she told the chat show host of her reaction to landing the role.

She got emotional as she said: 'I kept spontaneously crying, and I feel like I’m probably going to do it now.

'Growing up watching TV, I never saw someone on TV that I could identify with, let alone a superhero.'

The Orange Is The New Black actress, who is herself attracted to women, expressed elation Tuesday at her casting as a gay Batwoman.

'The Bat is out of the bag and I am beyond thrilled and honored. I’m also an emotional wreck.. because this is a childhood dream,' she wrote on Instagram.

'This is something I would have died to have seen on TV when I was a young member of the LGBT community who never felt represented on tv and felt alone and different. Thank you everyone. Thank you god,' wrote the Australian bombshell.

Ruby will be playing Batwoman, whose legal name is Kate Kane, on a CW show, Entertainment Weekly had reported that day.

Per the logline, as quoted by the magazine: 'Armed with a passion for social justice and a flair for speaking her mind, Kate Kane soars onto the streets of Gotham as Batwoman, an out lesbian and highly trained street fighter primed to snuff out the failing city’s criminal resurgence.'

The logline qualifies: 'But don’t call her a hero yet. In a city desperate for a savior, Kate must overcome her own demons before embracing the call to be Gotham’s symbol of hope.'
